12 Claims.

This invention relates to a machine for ar= ranging small articles for packing into containers, providing for inspection of such articles, and inserting them into their containers. The machine 5 will be described with reference to the arranging and packing of shot shells, but it will be understood that its utility is not limited to this particular field.

The specific objects of the invention will aplll pear from the following description of the purpose and accomplishments of the'machine, it being understood that the several parts of the complete machine are capable of use both separately and in conjunction with other mechanisms.

Shot shell loading machines are made to deliver shells loaded and ready for packing in an upright position. These shells comprise flanged heads, and for the purpose of effective packing it is necessary that alternate shells be in reversed position, the head of one shell standing opposite the mouth of adjacent shells. The present machine provides means for receiving shells in an upright position from the loading machine, automatically reversing the position' of alternate shells, and delivering the shells thus arranged to an inspection table where they remain aligned and in proper alternate arrangement a suiiicient time to permit visual inspection.

From the inspection table the shells are moved in groups, preieraoly of an odd number, into the containers in which they are to be packed. A row or five shells is slid into the container, the container is then automatically lowered a distance corresponding to the height of the row of shells which has been placed therein, a second row is put in place and the container is again lowered; this operation being repeated until the container is full. The final downward move- 40 ment of the container stops the operation of the devices which feed shells into the container, per= mitting the full container to be removed, an empty container put in place, and the container holdor restored to its uppermost position.- When 45 this has been done, the operator again starts the machine and the filling of the container is repeated. It is desirable that certain identifying legends be printed on the containers as they are filled. For, this purpose, means are provided, op-

50 crating in conjunction with the container filling means, for feeding the containers over a print roll provided with the proper legend and for stopping the' print roll and container feeding means i with the container filling means. 55 A representative embodiment of mechanism 1935, Serial No. 35,028 (Git: 226-16) for accomplishing these purposes is illustrated in the accompanying drawings, in which:

The machine is prefer sly mounted on a bench or table 29. Power for the moving parts is secured from a motor 2| which, through a belt 22 and pulley 23, drives a shaft 24. The bearing of shaft 24 is in a casting 25 which supports all parts of the shell receiving and reversing mechanism. Shells are received from the shell loading machine through a trackway identified generally by the numeral 26, said trackway comprising a suitable support and side bars 21 and 28 so spaced from the support as to furnish a channel for receiving shell heads and thus supporting the shells in an upright position, as clearly illustrated in Fig. 3. The trackway 23 communicates with a second trackway extending transversely of the machine and formed in the casting 25. A- belt 29 passing over a pulley 30 in an arm 3| of casting 25 and a second pulley on the shaft 24 furnishes a means for moving the shells delivered from the trackway 26. For movement onto the belt 29 the shells are guided between an angle plate 32 secured to the casting 25 and a second upright plate 33 pivoted to the casting 25 at 34 and urged inwardly by a suitable spring, such as 35. The free end of plate 33 is curved inwardly, as illustrated in Fig. 2, to direct shells onto the belt 29. When the movement of shells onto belt 29 is obstructed, as shown in Fig. 2, the plate 33 is swung about its pivot by the shells advancing through trackway 26 and the shellsmove across the belt 29, the belt sliding under them, and are directed into an outlet chute 35 by the turned end 31 of a guide plate 38 secured to the casting 25 opposite the leg of angle plate 32 which extends parallel to the belt 29. Suitable undercut blocks 39 and 40secured to the casting25 furnish a channel for receiving the flanged shell heads, thus holding the shells in anupright position a they are carried along by the belt 29. c

The shells are moved transversely off-from the belt 29 into a reversing chamber identified generally by numeral 4| by means of a pusher 42, being aligned with the pusher by engagement with a stop 4| I, preferably secured to or integral The pusher 42 is supported for rectilinear movement in an arm 43 of casting 25 and is urged forward by a spring 44 tensioned between the arm 43 and a stud 45 extending from the pusher. The pusher comprises an upwardly extending head 46, suitably curved to engage the periphery of a shell, and a lug 41 for engagement by a roller 48 on a lever 49 pivoted at 50 in the casting 25 and actuated through a roller 5| thereon by a cam 52 on the drive shaft 24. Said cam 52 comprises two lever operating lobes so that the pusher 42 is reciprocated twice, delivering two shells to the reversing chamber 4|, during each revolution of the shaft 24. In the reversing chamber the two shells thus delivered are placed in a horizontal position, each being reversed with respect to the preceding one, so that the head of each lies opposite the mouths of those adjacent on either side. The mechanism for this purpose may be constructed as follows:

A shell reversing bar 53 (Figs. 2, 4 and 5), suitably supported and guided for rectilinear movement in the casting 25, is reciprocated by a box cam 54 on the drive shaft 24. Said cam may conveniently be formed in the pulley 23 by which shaft 24 is driven. The member connecting the reversing bar 53 with the box cam 54 is identified by the numeral 55 and comprises a laterally extending roller 56 received in the track of the box cam, Member 55 comprises a base block "I 551, the position of which is determined by a tension adjusting screw 558 threaded into the top of the member 552 and held in adjusted position by a lock nut 559. Thus, the connection between the member 55 and the reversing bar 53 is sufliciently rigid to enable said bar to operate on shells in the manner to be described but will slip in the event that a shell becomes jammed and offers excessive resistance to the movement of the bar 53. This is of importance since the application of a crushing force to the shells might result in an explosion.

When the connecting member 55 has thus been displaced upon the bar 53 it is necessary that it be automatically restored to its initial position in order to reciprocate the bar 53 in proper synchronism with the movements of the pusher heretofore described. For this purpose, studs 550 (Fig. 5) and 56I (Fig. 2) extend downwardly from the reversing bar 53 near its ends. Normally these studs just clear the adjacent parts of the frame casting 25 at the ends of the reciprocating movements of bar 53. Should a shell become jammed, for example in the position illustrated in Fig. 5, with the reversing bar moving to the right, the connection member 55 will slide along the bar 53 toward the right. When member 55 reaches the limit of its movement in this direction and starts its reverse movement, it will .carry the bar 53 along with it until the stud 563 engages the adjacent surface 562 on the frame casting; thereupon the movement of bar 53 is stopped, and the connecting member again slides on this bar until it assumes its normal position thereon. The reciprocating bar thereafter functions in normal manner without the necessity for any manual readjustment.

The box cam is arranged to reciprocate the reversing bar 53 once during each revolution of shaft 24, while the pusher 42, as heretofore shown, delivers two shells during each revolu tion of shaft 24. Said shells are moved by the pusher 42' from belt 29 onto the reversing bar 53; thus, when one shellis delivered the pusher will be moving in one direction, say to the right, and when the next shell is delivered it will be moving in the opposite direction. The part of the reversing bar 53 which reciprocates-within the reversing chamber 4| is provided with ashell head receiving notch 51. By the engagementf of shell heads in this notch successive shells are.

the premature delivery of the shells and serves to hold them as delivered in a position transverse to the short delivery chute 6|. Normally the shells thus delivered drop through a gap 8 in the floor of chute 6| onto an inspection table 62. If the inspection table is full, as illustrated in Fig. 6, the last shell thereon partly bridges the gap 6 and additional shells delivered from the reversing chamber are pushed across the gap 6H and delivered through an overflow chute 63 where is preferably turned laterally, as shown in Fig. 2, so that overflow through both chute 58 and chute 38 is directed into the same receptacle. The weighted gate 59 prevents shells in the chute 6i. rolling back into the reversing chamber.

vThe inspection table'62, which is preferably inclined as illustrated in Fig. 1, is of a width slightly greater than thelength of a shot shell and comprises low front and rear guides d'and 55. Along the back of the inspection table adjacent the guide 6d is a mirror 65 by whichthe operator at the front of the machine is enabled to fully inspect the row of shells on the table.

Means are provided for delivering shells in groups from the inspection table to a carton or other container suitably held to receive a group p of shells, for then moving the container-to a position to receive a second group of shells, and for repeating the shell and container movements until the container is full. One form of mechanism for this purpose is illustrated in the drawings, particularly Figs. 2A, 8 to 12, 14, l6, l7 and 18. frame or casting til. Thedrive shaft 252 is connected through a universal Joint with a transmission shaft 6&3 carrying a second universal joint 59 connecting with a short shaft it having a bearing in the casting El. Fixed to the shaft iii is a bevel pinion ll meshing with a bevel gear pinion l2 loosely mounted on a transversely extending shaft 73 to which it is connected by means of a clutch member '7 provided with clutch teeth l5 engaging corresponding teeth on the hub of bevel pinion E2. The clutch member Ed has a spline connectionwith shaft i3, is urged into the clutch closing position by a spring l5, and is retracted to stop the shaft 73 in a manner to be hereinafter described.

The receptacle holding and moving means is supported and guided for vertical movement upon an upright bar ll secured to the casting G7. The holder comprises a back indicated generally by the numeral l8 having a part adapted to embrace the bar 70 and guide the holder for vertical movement thereon. A bottom plate l9 and an end plate 86 having inwardly turned edge portions, and a short lip or top plate 8M, are secured to the back 78. The frame thusformed receives a container till (Fig. 9) which preferably comprises a cover 8i i, held in extended position by engagement with the edge of the inspection table, and inside closing flaps M2 and BIS. A retainer 8i hinged to the back 13 at 85 comprises an elongated and weighted head which engages the upper and outer portions of the container to hold it in the holder frame, from which it may be readily removed by lifting the retainer. The movement of retainer 8| about its pivot 85 is limited by the engagement of a pin 86 on the holder back 58 in an elongated slot 8? in the retainer.

The holder is drawn upwardly by a spring 82 tensioned between a stud 83 secured to the bar l? and a stud 8% attached to the holder. The

The mechanism is chiefly supported on a means for stopping the holder in a depr polition may comprise a ratchet plate 38 secured to the holder back 18 and provided with a series of upwardly facing shoulders or ratchet teeth 88 adapted to cooperate with pawls 9i! and 9!. Referring to Fig. 10, it will be noted that there are flveteeth as which are equally spaced and a supplemental tooth 92 spaced at a greater distance from the uppermost 01 the teeth 89. When the receptacle holder is in its uppermost position, as illustrated in Fig. 8. the floor or bottom plate i9 is substantially in alignment with the inspection table t2. Both the table and the holder are inclined a suflicient amount to enable shells released from the inspection table to roll into the holder. However, means are provided for positively moving a group of shells into the holder, as

hereinafter described. when the first group of shells has been thus placed in the holder it is necessary todepress the holder against the tension of spring 82 an amount substantialLv equal to the thickness of the row of shells therein. This is accomed by means of the pawl as. said pawl is pivoted at as to a lever on pivoted at 95 in the supporting casting ti. Pawl 9! is urged to position to engage the ratchet teeth 83 and 92 by suitable means such as a spring at. The opposite end of lever 96 carries a roller 91 drawn into engagement with the periphery of a cam 98 on shaft 73 by a spring 99. The throw of pawl 98 is equal to the spacing of tooth 92 from the uppermost tooth 23d, hence it has a short idle move= ment (see r g. 10) except when it engages tooth 92. The first four rotations of shaft is each ole-=- press the container holder by an amount equal to the spacing of the teeth 8%, and it is held in successive depressed position by retaining pawl 963. The extra long step of movement between teeth 89 and tooth 92 is provided to carry a full container entirely below the level of theinspection table (broken line position, Fig. 9), and thus facilitate its removal. Means are provided, as hereinafter described, for disengaging the clutch i l and thus stopping the machine as the con= tainer holder reaches its lowermost position.

This condition is illustrated in Fig. ii. The holder is held down by pawl 95, roller 9? being engaged by the highest part of cam The con= tents of the container are held therein by a plate 62! extending downwardly from the end of the v inspection table $2, and secured near its lower end to casting ill. The operator may remove the container and contents by swinging the cover til i, lifting the retainer 85, and moving the container forward.

The mechanism for retaining the shells on the inspection table and for delivering them to a container on the container holder in successive groups as the container holder is depressed may be constructed as follows: l

The shaft l3 carries a cam lllil controlling a cam follower lever till provided with a cam engaging roller m2 and fixed to a shaft its supported in brackets extending from the casting ill. A spring ltd holds the roller use in contact with the periphery of the cam Hill. 'The opposite end of shaft IE3 carries an arm Hi5 comprising a head its having a longitudinal groove for receiving a sliding block Hill apertured to receive a stud extending from a bar not adapted to reciprocate in a channel formed in part by plates H38! in the casting 51. To the bar its is secured a vertically extending arm S09 and from the upper end of arm I69 certain supporting members extending forwardly above the inspection table. To one or 1 container.

feed pawl H3 preferably comprising two fingers H4 spaced to provide clearance for the shell holding spring finger III and adapted to engage between adjacent shells on the inspection tablein the manner illustrated in Figs. 8 and 9. The bar I08, and with it the feed pawl H3, reciprocates in each revolution of the shaft 13 a distancesubstantially equal to the depth of the container on the container holder, being advanced by spring I04 as the rotation of shaft 13 brings the low part of cam I opposite the cam following roller I02. The drawings illustrate a mechanism for packing a container with twenty-five shells in five rows of five each.- Fig. 8 shows the feed pawl H3 in retracted position, five shells being ahead of the pawl in position to be thrust into the container, which is in its uppermost position, by the advancement of feed pawl H3. Fig. 9 shows the feed pawl in an intermediate position, the group of five shells being partly moved into the container. To hold the shells on the inspection table, except when they are being moved by the feed pawl I I3, a holding finger or lever I I5 having a slightly upturned end I I6 is pivoted to the frame at I I1 and controlled by a cam H6 on the forward end of shaft 13. The relation of cam H8 to cam I00 is such that the end H6 of finger I I5 is lowered to release the shells just before the pawl I I3 is moved to advance them. As the pawl H3 reaches the limit of its forward movement, a roller H9 on lever H5, which is held in engagement with cam H8 by a spring I20, rides 011 from the high part of cam H8, permitting spring I to again lift the end H6 of finger H5 into shell holding position.

It is necessary that the operations of shell feeding and container displacement be interrupted when each container is full, in order to permit the machine operator to remove the full container, restore the container holder to its uppermost position, and place an empty container thereon. For this purpose, means are provided for automatically disengaging the clutch 14 after the desired number of revolutions of the shaft 13 and the corresponding number of steps of movement of the container holder. Mechanism for this purpose may be constructed as follows:

To the shaft 13 is secured a pinion I2l which drives a gear I22 pivoted on a stub shaft extending from a. plate of the casting 61.- The pinion I2I and gear I22 are in the illustrative machine in a five-to-one ratio, the gear turningonce for five revolutions of the pinion. Moved by the gear I22 and preferably formed as a part thereof is a cam I23 controlling a cam follower I24 associated with a lever I25 pivoted in the frame. Extending from lever I25 is a stud I26 received in a cam track I21 in the periphery of the clutch member 14. It will be remembered the clutch 14 is urged into engaging position by spring 16. The engagement of stud I26 with the active surface I28 of cam track I21 will withdraw the clutch, as clearly seen in Fig. 2A. The configuration of the cam I23 on gear I22 will, as shown in Fig. 11, permit the lever I25 to swing forward and cause the engagement of stud I26 in cam track I21 near the end of one revolution of gear I22 or five revolutions of pinion I2I. Since the container is adapted to hold five layers of shells and one layer is inserted on each revolution of To a second support H2 is pivoted a shaft 13 and pinion I2I, it is apparent'that the 1 clutch will be disconnected and the machine stopped immediately after the container is full. The container holder is at this time in its lowermost position, and is held there by pawl 6| and cam 66 as heretofore described. The operator now removes the filled container and restores the container holder to its uppermost podtion. For this purpose, it is necessary to displace both pawls 80 and ill. Pawl 90 is an integral part of an elbow lever pivoted at I23 and urged to effective position by a spring I30. Extending rearwardly from the upper portion of pawl 00 is a pin I3I which stands in the path of movement of the upwardly extending arm of an elbow lever I32 likewise pivoted at I 23. To the horizontally extending arm of elbow lever I32 is attached a link I34 extending downwardly through the table and suitably joined to a link I 35 connected with an operating treadle I36. Link I34 and associated parts are drawn upwardly by a suitable spring such as I31. The vertically extending arm of elbow lever I32 is adapted to engage not only the pin I3I on pawl 90 but also a pin I36 on pawl 0|. Thus, by depressing the treadle I36 and rocking the elbow lever, both pawls 00 and 3| are disengaged from the ratchet teeth 63, and the container holder is restored to its uppermost position by its spring 65, being stopped in said uppermost position by its engagement with a block I30 secured to the track bar 11. Preferably a buffer I40 of a suitable resilient material is secured to the top of the container holder and engages in a suitable recess in the block I30, as clearly shown in Fig. 8. vBlock I39 likewise supports a downwardly and forwardly extending finger I which guides the inner closing flap ,6I2 as the container holder is lowered, preventing damage to this flap in the movement of the shell feeding pawl H3. The container holder being restored to its uppermost position and an empty container placed thereon, the machine is again set in operation by withdrawing the stud I26 on lever I25 from cam groove I21 in the clutch collar. For this purpose, lever I 25 is secured to one end of a short shaft having a. bearing in the supporting casting 61 and carrying at the opposite end an arm I42 to which is connected 9. link I43 extending through the bed of table 20 and joined to a link I44 drawn upwardly by a spring I45 and adapted to be depressed by the operation of a treadle I46. Upon the withdrawal of the stud I26, spring 16 thrusts the clutch member 14 into engagement with the constantly rotating pinion 12 and a second cycle of operation is initiated, which cycle will again be automatically interrupted when the container on the holder has been filled.

Means are provided for sounding an audible signal in the event that the feed pawl I I 3 has not performed its complete forward movement. It will be recalled that this pawl is advanced by the spring I04 to feed a row of shells into the container, its movement by the spring being permitted by the withdrawal of the high part of cam I00 in the revolution of shaft 13. If the movement of the feed pawl is obstructed and the pawl Y shaft 18 av center.

The bell ringing mechanism is illustrated in detail in Figs. 17 and 18. .The bell ringing device comprises a hammer 9 extending from a. block I50 pivoted at Hit in the counter-weight it'd and normally held in contact with the hell by a compression spring I52. n the side of the counter-weight I48 adjacent the roller it? on arm it! the block I50 has a wedge-shaped head I53. As clearly shown in Fig. 17, this head stands opposite the lowest part of the cam Hit and is so spaced therefrom that if the roller N12 is in contact with the cam ltd the projecting end I56 of the roller shaft passes between the periphery of the cam and the wedge-shaped head I58 of the bell ringing device. However, if the roller I02 is held in any other position than in proper engagement with the periphery of cam Hill the part 555 will engage the edge or cam surface of the head 553 as illustrated in Fig. 17, rocking the member ltd about pivot I55 to compress the spring m2 and retract the hammer. As the part 3 moves past and releases the head 953 the hammer will be propelled against the bell.

Means are provided for operating a container feeding and printing mechanism in conjunction with the container filling or packing devices above described. It is desirable that certain data be imprinted upon the container in conjunction with the packing, such data to indicate certain characteristics of the contents, the date of packing, and other identification data if desired. For the purpose of operating print rolls and feeding the full containers thereto, there is provided a gear H55 meshing with the gear I22 and carrying a sprocket wheel H56. Said sprocket wheel supports a sprocket chain l5? (Figs. 2E and 15) loosely mounted on a shaft ldt and adapted to drive said shaft througha friction clutch mechanism comprising a plunger I59 urged by a spring Nit into a notch in the hub ltl of said sprocket wheel. Shaft l58 carries agear H62 adapted to drive the inking and printing rolls illustrated in Fig. 2B. Said shaft H58 likewise carries sprocket wheels I63 receiving sprocket chains ltd carrying feeding lugs i155 (Fig. 13). The mechanism is arranged to print desired legends on the container covers, the covers being open as the containers are fed past the printing rolls by engagement with the feeding lugs 965. The operator, upon removing a filled container from the container holder of the packing unit, closes the inside fiaps to retain the contents, leaving the cover open (see Fig. 9). A printing roll, as ltl, is provided with the legend to be imprinted, the container cover passing between the printing roll and a presser roll M55. To properly align and position the container and cover, a positioning frame comprising bars its and I69 is secured to the table 29, and a cover holding finger H0 is arranged as shown in Fig. 2B. A container placed in the position shown in dotted lines in this figure will be picked up by lugs l5? and moved past the printer; the printer and lugs being connected in the manner described the printing point on each cover is the same. By reason of the one-way clutch 859 the printer may be manually operated independently of the packer, and thereafter automatically synchronized with the packer. The upper reaches of the sprocket chain I65 are substantially flush with the table surface, as clearly shown in Fig. 13, and the containers, having the covers properly imprinted, are delivered therefrom to the table in position for cover closing and removal.
